Hai mama, aku faham lah panik nak dengar "cyst" tu sewaktu scan first trimester, tapi luteal cyst memang sangat common dan mostly akan resolve sendiri by second trimester je, doktor aku dulu cakap sama je! A few of my mum friends went through this and memang hilang masa trimester kedua without any drama, so don't worry too much ye. Just make sure follow up dengan doktor korang untuk monitor, and they'll confirm sudah gone on the next scan, habis cerita! Take care, mama.
